diffractive telescope, Fresnel lens, color correction
A design example of diffractive telescope is presented and the aperture of objective is 3 meters. The operating wavelength of the system is 7.7 - 10.3μm and spectral bandwidth ｜Δλ/λ｜ is about 1/3. It is shown that the system approximately attains diffraction limit. We developed a small scale diffractive telescope and its＇ image quality was perfect.
